Indicator C3 — Duplicate or Near-Duplicate Projects

AI-verified / Na-verify ng AI Data as of October 21, 2026

Duplicate or Near-Duplicate Projects

Very similar descriptions within ~100m or identical coordinates across contracts/years.

This is a statistical anomaly or indicator worth examining — not proof of wrongdoing, fraud, or corruption against any person.

Indicator: contracts 24AJ0025 and 23AJ0125 have near-identical descriptions about 259 m apart (funding years 2023, 2024; ₱48.13M, ₱18.98M). Worth checking whether they cover the same works. The second project may be an earlier phase or a continuation that was not labeled as such.

How this was checked

publish · confidence 0.85

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The only distinguishing marker is 'Phase III' in the first title, while the second title has no phase or package marker. Per rule guidance, if one title has a phase/package marker and the other has none, this is a classic 'unlabelled twin' case and should be published. The locations are close (259 m), and the titles are otherwise near-identical, both referring to protection works along Agno River in Barangay/Brgy. Tampog, Bayambang, Pangasinan. All required record IDs and URLs are present.
